Flat Lay — Side-by-Side Results
Prompt
"Top-down flat lay on a cozy bedroom duvet: a 20s woman with shoulder-length wavy dark hair leans into the corner of the frame, looking up toward the phone camera with a relaxed half-smile, wearing an oversized oatmeal hoodie and soft shorts as if mid “morning reset” story. Neatly arranged around her are an iced matcha, open journal with scribbles, a skincare serum, lip balm, wireless earbuds, sunglasses, and a messy claw clip, all balanced on a clean neutral surface. Soft window daylight, casual unfiltered vibe, like a real Instagram story snapshot."

- Reliable scene coherence when generating multi-object arrangements (consistent lighting and shadow logic across items)
- Flexible quality tiers (8/16/32 credits) for quick concepting vs premium hero flat lays
Seedream 4.5 Strengths
- Built-in image-to-image editing for refining an existing flat lay (swap props, adjust styling, iterate without restarting)

- Versatile styles for flat lays (minimal studio, lifestyle, editorial, seasonal, playful brand palettes)
- Straightforward per-image pricing (16 credits) for predictable budgeting during iteration
Verdict
If you need a flat lay generated from scratch with tight prompt control—especially when you’re specifying exact objects, arrangement rules, or a branded prop list—GPT-Image 1.5 is the stronger choice. Its prompt adherence and fidelity make it well-suited to “brief-style” flat lay prompts where layout accuracy matters.
If your workflow is iterative—starting from a reference flat lay and repeatedly tweaking items, colors, or styling—Seedream 4.5 stands out thanks to image-to-image editing and high-resolution output. For teams doing many small revisions to nail the final arrangement, it can be the more efficient path even at a flat 16 credits per image.
